Well, finding the right person is difficult for many whether they identify as being 'empath' or 'not; hence, all those dating sites and apps and options.
All I can say is don't base your entire life off of your parent's unhappy marriage. You don't have to be like them. My grandparents had a great marriage but none of their children (with the exception of one) have stable, healthy, happy marriages from what I can see so it's not all about them.
It's also a matter of trial and error. You're gonna make mistakes even with your empath ability so no point in really fearing them. It doesn't actually lessen the blow anyway.
So good luck! Hope romantic love finds you.
